Therefore, the method for cleaning the camera 100 according to the embodiment of the invention has the advantages of energy saving, environmental protection and small equipment load.

The method of cleaning the camera 100 according to the embodiment of the present invention will be specifically described below in conjunction with the camera 100 according to the embodiment of the present invention. As shown in fig. 1 to 12, a camera 100 according to an embodiment of the present invention includes a body 1, a camera, a housing 2, and a cleaning assembly.

The camera and the housing 2 are arranged on the body 1, and the camera is positioned in the housing 2. Specifically, the housing 2 is made of a light-transmitting material, and at least part of the outer surface of the housing 2 is spherical. For example, the housing 2 is a hemispherical glass housing.

As shown in fig. 1 to 12, the cleaning assembly includes a mounting frame 3, a cleaning member 4, a driving base 5, a driving member 6, a nozzle 8, and a reset member.

The mounting frame 3 is arranged on the body 1. Specifically, the mounting frame 3 is annular, and the mounting frame 3 is fitted around the outer peripheral side of the housing 2.

The cleaning member 4 is located outside the housing 2, and the cleaning member 4 is movably provided on the mounting frame 3 such that the cleaning member 4 has an initial position and a cleaning position, and the housing 2 can be cleaned when the cleaning member 4 moves between the initial position and the cleaning position. Specifically, the cleaning member 4 is rotatably provided on the mounting frame 3, and the cleaning member 4 is rotatable between an initial position and a cleaning position and is brought into contact with the outer surface of the housing 2 during rotation to clean the housing 2. The shape of the cleaning element 4 is adapted to the outer surface of the housing 2, so that the contact surface of the cleaning element 4 with the outer surface of the housing 2 can be made larger for better cleaning of the housing 2. For example, the contact portion of the cleaning member 4 with the outer surface of the housing 2 is arc-shaped, and the contact portion of the cleaning member 4 with the outer surface of the housing 2 is made of a rubber material.

As shown in fig. 3, 4, 5, 8, 11 and 12, the driving seat 5 has a driving chamber 7 and a first inlet 9 communicating with the driving chamber 7. The drive member 6 is movably arranged in the drive chamber 7 such that the drive member 6 has a first position and a second position, the first inlet 9 being adapted to feed a medium for pushing the drive member 6 from the first position to the second position. The driving member 6 is connected to the cleaning member 4, and the driving member 6 can drive the cleaning member 4 to move from the initial position to the cleaning position during the process of moving from the first position to the second position. The medium (power source) with certain pressure is introduced into the driving cavity 7 to drive the driving piece 6 to move, so that the cleaning piece 4 is driven to move from the initial position to the cleaning position, and the cleaning work is finished. Specifically, when the driving member 6 is in the first position, the cleaning member 4 is in the initial position; when the driving member 6 is in the second position, the cleaning member 4 is in the cleaning position.

Optionally, the medium comprises a liquid, a gas. For example, the medium is water.

In step S1, after the feeding device stops feeding the medium into the driving chamber 7, the reset member drives the cleaning member 4 to move from the cleaning position to the initial position, and drives the driving member 6 to move from the second position to the first position.

As shown in fig. 1 to 12, a reset member is connected to the mounting frame 3 and the cleaning member 4, and the reset member can drive the cleaning member 4 to move from the cleaning position to the initial position. Specifically, the restoring member is an elastic member 14, the elastic member 14 can be elastically deformed, one end of the elastic member 14 is connected with the mounting frame 3, and the other end of the elastic member 14 is connected with the cleaning member 4. The elastic piece 14 is elastically deformed when the driving piece 6 drives the cleaning piece 4 to move from the initial position to the cleaning position in the process of moving from the first position to the second position; when the medium is stopped, the cleaning member 4 returns under the action of the elastic member 14 and drives the cleaning member 4 to move from the cleaning position to the initial position, so that the cleaning member 4 is reset, and the driving member 6 can be driven to reset (the driving member 6 is driven to move from the second position to the first position). For example, the elastic member 14 is a torsion spring.

In some implementations, the drive seat 5 has a third inlet (not shown in the figures) in communication with the drive chamber 7, the third inlet being adapted to be fed with a medium in order to push the drive member 6 from the second position to the first position. The driving member 6 is connected to the cleaning member 4, and the driving member 6 can drive the cleaning member 4 to move from the cleaning position to the initial position during the process of moving from the second position to the first position. Specifically, the first inlet 9 and the third inlet are located at two sides of the driving member 6, the first inlet 9 is connected to the medium to push the driving member 6 to move from the first position to the second position, and the third inlet is suitable for the medium to push the driving member 6 to move from the second position to the first position, so that the cleaning member 4 can be driven to reciprocate between the cleaning position and the initial position.

In step S1, medium is continuously fed into the drive chamber 7 by the supply device, so that the medium in the drive chamber 7 can enter the lance 8 and be sprayed onto the housing 2. Under the flushing of the medium sprayed to the housing 2, impurities on the surface of the housing 2 can be flushed clean.

As shown in fig. 1 to 12, the spout 8 has a second inlet and a plurality of second outlets 12, each second outlet 12 being directed towards the casing 2. Specifically, the nozzle 8 is provided on the mounting frame 3, the nozzle 8 is annular, the nozzle 8 is provided on the outer side of the housing 2 in a surrounding manner, and the plurality of second outlets 12 are provided on the nozzle 8 at intervals in the circumferential direction.

The drive seat 5 also has a first outlet 10 communicating with the drive chamber 7, the first outlet 10 communicating with the second inlet, the first outlet 10 communicating with the first inlet 9 when the drive member 6 is in the second position. The inlet of the nozzle 8 communicates with the drive chamber 7 and the outlet of the nozzle 8 is directed towards the housing 2. The medium introduced into the drive chamber 7 can thus be introduced into the nozzle 8 (inlet) via the first outlet 10 and the housing 2 can be rinsed via the second outlets 12 (outlet of the nozzle 8) in order to further clean the housing 2.

In some embodiments, in step S1, the feeding means charges the medium into the driving chamber 7 for a period of 10 seconds or longer. This allows the housing 2 to be subjected to a medium rinse for a longer period of time, thereby facilitating cleaning of the housing 2. After the cleaning, the cleaning member 4 can wipe the housing 2 again during the resetting process, so that the cleaning member 4 can clean the housing 2 of water mist and dust, thereby cleaning the housing 2 better.

In some embodiments, step S1 is performed a number of times equal to or greater than 2. This allows the cleaning element 4 to wipe the housing 2 a plurality of times and the medium to rinse the housing 2 a plurality of times. So that the housing 2 can be cleaned more effectively. For example, step S1 is performed 3 times each time the housing 2 is cleaned.

In some embodiments, a control valve is provided on the supply device, by means of which control valve the flow and/or pressure of the medium into the drive chamber 7 is controlled in step S1. Specifically, the supply means comprises a supply conduit communicating with the drive chamber 7, on which supply conduit the control valve is arranged. When the medium is introduced into the driving cavity 7, at least one of the flow rate and the pressure of the medium in the supply pipeline is regulated by regulating the control valve, so that the medium introduced into the driving cavity 7 can drive the driving piece 6 to move, and the medium discharged from the outlet of the spray pipe 8 has enough pressure.

As shown in fig. 1 to 12, in some embodiments, the cleaning member 4 is provided with a rotation shaft 13, and the rotation shaft 13 is rotatably provided on the mounting frame 3. For example, the number of the rotating shafts 13 is two, both ends of the cleaning member 4 are connected with one rotating shaft 13, and the elastic member 14 is sleeved on at least one rotating shaft 13. The axial direction of the rotation shaft may be the front-rear direction, which is indicated by an arrow in fig. 1.

As shown in fig. 1 to 4, in the first embodiment, a part of the rotation shaft 13 protrudes into the drive chamber 7. Specifically, a rotary shaft 13 is rotatably provided on the mounting frame 3 and a portion of the rotary shaft 13 extends into the drive chamber 7.

The driving piece 6 is a blade, the blade is connected with the rotating shaft 13, the thickness direction of the blade is perpendicular to the axial direction of the rotating shaft 13, and the blade is rotatably arranged in the driving cavity 7. Thereby, the blade can be made to rotate around the axis of the rotating shaft 13 and the driving cavity 7 can be (substantially) blocked, and medium can easily impact the blade and drive the blade to move from the first position to the second position when the medium is introduced into the driving cavity 7. For example, the thickness direction of the blade is vertical in the front-rear direction.

As shown in fig. 3, in some embodiments, the drive chamber 7 includes a first wall 17, a second wall, an arcuate surface 18, and a planar surface 19. The first wall surface 17 and the second wall surface are disposed opposite to each other in the axial direction of the rotating shaft 13, and the first wall surface 17 and the second wall surface are connected to the arc surface 18 and the plane 19. The arcuate surface 18 and the plane 19 are disposed opposite to each other, and both ends of the arcuate surface 18 in the extending direction (arcuate) are connected to both ends of the plane 19, respectively. During rotation of the vane, the vane is slidably connected to the first wall 17, the second wall, the arcuate surface 18 and the planar surface 19, and the first inlet 9 and the first outlet 10 are adjacent to both ends of the arcuate surface 18 in the extending direction, respectively. Thus, the fluid medium is easy to rotate with the blade and difficult to enter the first outlet 10 before the blade moves to the second position; after the vane has been moved to the second position, fluid medium may be passed into the first outlet 10.

In some embodiments, as shown in fig. 3, the blade includes a first section 15 and a second section 16 that are connected. The rotating shaft 13 is arranged in the first section 15, the thickness of the first section 15 is larger than that of the second section 16, the surface of the first section 15 far away from the second section 16 is an arc surface suitable for being in sliding connection with the plane 19, and therefore the surface of the first section 15 far away from the second section 16 is always in sliding connection with the plane 19 in the rotating process of the blade. Alternatively, the face of the second segment 16 remote from the first segment 15 is a cambered surface adapted for sliding connection with the cambered surface 18.

In a second embodiment, as shown in fig. 5 to 8, the driving chamber 7 is a circular arc chamber, and the driving member 6 is a circular arc rod and is adapted to the shape of the driving chamber 7. Specifically, the center of the drive chamber 7 coincides with the center of the drive member 6, and the shape of the drive member 6 is (substantially) the same as the shape of the drive chamber 7 in a cross section perpendicular to the extending direction of the circular arcs of the drive member 6 and the drive chamber 7. For example, in a cross section perpendicular to the extending direction of the circular arcs of the driver 6 and the driving chamber 7, the shape of the driver 6 and the shape of the driving chamber 7 are both quadrangular.

The drive member 6 is slidably arranged in the drive chamber 7 in the (circular arc) extension direction of the drive chamber 7 and is rotatable relative to the drive seat 5 such that the drive member 6 has a first position and a second position, the first inlet 9 being adapted to let in medium for pushing the drive member 6 from the first position to the second position. The driving member 6 is connected to the cleaning member 4, and the driving member 6 can drive the cleaning member 4 to move from the initial position to the cleaning position during the process of moving from the first position to the second position. The medium (power source) with certain pressure can be introduced into the driving cavity 7 to drive the driving piece 6 to slide, and the driving piece 6 slides along the arc-shaped extending direction of the driving cavity 7 to enable the driving piece 6 to rotate relative to the driving seat 5, so that the cleaning piece 4 is driven to move (rotate) from the initial position to the cleaning position, and the cleaning work is completed. Specifically, when the driving member 6 is in the first position, the cleaning member 4 is in the initial position; 6 the drive member 6 is in the second position and the cleaning member 4 is in the cleaning position.

As shown in fig. 8, in some embodiments, the drive chamber 7 has a first end 20 and a second end 21 in its extension, the second end 21 being open, the first inlet 9 being adjacent the first end 20, the first outlet 10 being adjacent the second end 21, and one end of the drive member 6 extending out of the drive chamber 7 and being connected to the cleaning member 4. Thereby, the medium entering from the first inlet 9 can push the driving member 6 by the driving chamber 7 so that the first end 20 rotates in the direction of the second end 21 and during rotation the cleaning member 2 is driven to rotate. When the driving member 6 reaches the second position, the medium in the driving chamber 7 can enter the nozzle 8 from the first outlet 10.

As shown in fig. 9 to 12, in the third embodiment, the driving cavity 7 is a cylindrical cavity, the axial direction of the driving cavity 7 is consistent with the axial direction of the rotating shaft 13, the rotating shaft 13 is located at the axial position of the driving cavity 7, the blade comprises a connected blade body and a connecting ring, the connecting ring is sleeved on the rotating shaft 13, the blade body is slidably connected with the wall surface of the driving cavity 7, a partition piece 22 is arranged in the driving cavity 7, the partition piece 22 is connected with two axial wall surfaces of the driving cavity 7, the partition piece 22 is slidably connected with the connecting ring at the first radial end of the driving cavity 7, and the partition piece 22 is connected with the side wall of the driving cavity at the second radial end of the driving cavity 7. Specifically, the driving chamber 7 includes two circular wall surfaces axially opposite to each other in the driving chamber 7 and an annular side wall connected to the two circular wall surfaces, the partition 22 is connected to the two circular wall surfaces at both sides in the axial direction of the driving chamber 7, the partition 22 is connected to the annular side wall at the second end in the radial direction of the driving chamber 7, and the partition 22 is slidably connected to the circumferential side of the connecting ring at the first end in the radial direction of the driving chamber 7. Thus, when the driving member 6 (blade) rotates, the blade body cooperates with the partition 22 to divide the driving chamber 7 into two chambers, and when the blade body is not rotated to the second position, the first inlet 9 and the first outlet 10 are separated from the partition 22 by the blade body. When the blade body is rotated to the second position, the blade body may be in contact with the partition 22, at which point the first inlet 9 communicates with the first outlet 10.

In some embodiments, a baffle 23 is provided within the drive chamber 7, the baffle 23 being located between the first inlet 9 and the drive member 6 in the axial direction of the drive chamber 7. For example, the partition 22 includes two partition plates that are angled and spaced apart from the connecting ring. The baffle 23 is a rubber baffle, and a baffle 23 adjacent to the first inlet 9 is arranged in the driving cavity 7 so as to block the blade body positioned at the first position and prevent the blade positioned at the first position from blocking the first inlet 9. The baffle 23 is located circumferentially between the vane body and the first inlet 9, and when a medium enters the drive chamber from the first inlet 9, the vane body (and the rotary shaft 13) is pushed to rotate in a direction away from the baffle 23 until the vane body reaches the second position, so that the first inlet 9 and the first outlet 10 are communicated.

In some embodiments, the medium is at least one of a liquid medium and a gaseous medium. That is, the medium may be in a liquid state or in a gaseous state. In step S1, the supply device supplies a medium with a predetermined pressure into the drive chamber 7. The medium with the preset pressure can drive the driving piece 6 to move, so that the cleaning piece 4 is driven to wash the housing 2.

In some embodiments, the medium is water and the supply device is a high pressure water system of a fully mechanized coal face. The existing high-pressure water system of the underground fully-mechanized mining face is used as a supply device, so that the cost can be reduced, and the water supply difficulty can be reduced. For example, a downhole spraying device is used as a water supply device, and a spraying pipe communicating with the driving chamber 7 is provided in the spraying device so as to introduce high-pressure water into the driving chamber 7.

In some embodiments, the medium is a cleaning fluid. The downhole dust is oily or alkaline, and the adhesion force on the housing 2 is strong, so that when the camera 100 according to the embodiment of the invention comprises the spray pipe 8, the cleaning solution is used as a medium to clean the dust on the housing 2.

In some embodiments, the medium includes a liquid medium and a gaseous medium. Step S1 includes S11 and S12.

In step S11, a liquid medium is introduced into the drive chamber 7 by the supply device.

In step S12, a gaseous medium is introduced into the drive chamber 7 by a supply device.

Wherein, step S11 and step S12 are not sequential. That is, the supply device may introduce the liquid medium into the driving chamber 7 and then introduce the gaseous medium, or may introduce the gaseous medium and then introduce the liquid medium. For example, the supply means includes a liquid medium supply means and a gaseous medium supply means, both of which are communicated with the drive chamber 7 so as to introduce the gaseous medium or the liquid medium into the drive chamber 7.
